The 1987 Pacific hurricane season was the last year in which the Eastern Pacific Hurricane Center was the primary warning center for tropical cyclones in the eastern Pacific Ocean. The season officially started May 15, 1987, in the eastern Pacific, and June 1, 1987, in the central Pacific, and lasted until November 30, 1987. These dates conventionally delimit the period of each year when the vast majority of tropical cyclones form in the northeastern Pacific Ocean. Despite there being 20 named systems, five above the average, only four storms directly affected land. Hurricane Eugene was the first Pacific hurricane to make landfall in Mexico in July since the 1954 season and caused all of the season's three deaths and $142.12 million damage. Tropical Storm Pilar and Hurricane Norma also came close to land, with the former producing record rain in Baja California Sur. The remnants of Hurricanes Ramon and Norma caused rain in the Continental United States. Elsewhere, Peke was a central north Pacific hurricane that crossed the International Dateline and became a typhoon of the 1987 Pacific typhoon season. ==Seasonal summary== ImageSize = width:800 height:195 PlotArea = top:10 bottom:80 right:20 left:20 Legend = columns:3 left:30 top:58 columnwidth:270 AlignBars = early DateFormat = dd/mm/yyyy Period = from:01/05/1987 till:01/12/1987 TimeAxis = orientation:horizontal ScaleMinor = grid:black unit:month increment:1 start:01/06/1987 Colors = id:canvas value:gray(0.88) id:GP value:red id:TD value:rgb(0.38,0.73,1) legend:Tropical_Depression_=_<39_mph_(0-62_km/h) id:TS value:rgb(0,0.98,0.96) legend:Tropical_Storm_=_39-73_mph_(63-117 km/h) id:C1 value:rgb(1,1,0.80) legend:Category_1_=_74-95_mph_(119-153_km/h) id:C2 value:rgb(1,0.91,0.46) legend:Category_2_=_96-110_mph_(154-177_km/h) id:C3 value:rgb(1,0.76,0.25) legend:Category_3_=_111-130_mph_(178-209-km/h) id:C4 value:rgb(1,0.56,0.13) legend:Category_4_=_131-155_mph_(210-249_km/h) id:C5 value:rgb(1,0.38,0.38) legend:Category_5_=_>=156_mph_(>=250_km/h) Backgroundcolors = canvas:canvas BarData = barset:Hurricane bar:Month PlotData= barset:Hurricane width:11 align:left fontsize:S shift:(4,-4) anchor:till from:07/06/1987 till:09/06/1987 color:TS text:"Adrian (TS)" from:03/07/1987 till:07/07/1987 color:TS text:"Beatriz (TS)" from:05/07/1987 till:10/07/1987 color:TS text:"Calvin (TS)" from:15/07/1987 till:20/07/1987 color:TS text:"Dora (TS)" from:22/07/1987 till:26/07/1987 color:C2 text:"Eugene (C2)" from:24/07/1987 till:31/07/1987 color:TS text:"Fernanda (TS)" barset:break from:28/07/1987 till:03/08/1987 color:C1 text:"Greg (C1)" from:31/07/1987 till:09/08/1987 color:C3 text:"Hilary (C3)" from:03/08/1987 till:09/08/1987 color:TS text:"Irwin (TS)" from:13/08/1987 till:22/08/1987 color:C2 text:"Jova (C2)" from:26/08/1987 till:29/08/1987 color:TS text:"Oka (TS)" from:28/08/1987 till:30/08/1987 color:TS text:"Knut (TS)" barset:break from:29/08/1987 till:03/09/1987 color:C1 text:"Lidia (C1)" from:09/09/1987 till:16/09/1987 color:C4 text:"Max (C4)" from:14/09/1987 till:20/09/1987 color:C1 text:"Norma (C1)" from:20/09/1987 till:26/09/1987 color:C3 text:"Otis (C3)" from:21/09/1987 till:27/09/1987 color:C2 text:"Peke (C2)" from:30/09/1987 till:01/10/1987 color:TS text:"Pilar (TS)" barset:break from:05/10/1987 till:12/10/1987 color:C4 text:"Ramon (C4)" from:27/10/1987 till:31/10/1987 color:TS text:"Selma (TS)" barset:break bar:Month width:5 align:center fontsize:S shift:(0,-20) anchor:middle color:canvas from:01/06/1987 till:01/07/1987 text:June from:01/07/1987 till:01/08/1987 text:July from:01/08/1987 till:01/09/1987 text:August from:01/09/1987 till:01/10/1987 text:September from:01/10/1987 till:01/11/1987 text:October TextData = pos:(570,30) text:"(From the" pos:(617,30) text:"Saffir-Simpson Hurricane Scale)" Overall, the season continued the general trend in the 1980s of well above-average seasons in the East Pacific.〔 In 1987, there were 20 tropical storms, 10 hurricanes, and four major hurricanes, all were well above average, save the number of major hurricanes which was only slightly above normal. The former made 1987 the fifth most active season on record at that time. Today, 1987 is tied with the 1994 Pacific hurricane season and the 2009 Pacific hurricane season as the sixth most active on record. In the Central Pacific Hurricane Center's area of responsibility, one storm peaked at hurricane strength (Peke) and one peaked as a tropical storm (Oka). Two tropical storms entered this area of responsibility from the east by crossing 140°W.〔(【引用サイトリンク】title=The 1987 Central Pacific Tropical Cyclone Season )〕 The season lasted a total 171 days beginning with the formation of Adrian and early June and the dissipation of Tropical Depression Twenty on November 25. There was a total of 924 storms hours and 631 hurricane hours. By comparison, the long-term averages at that time were 161 season days, 875 tropical storm hours, and 664 hurricane hours. 397 advisories were issued, which was below the 1977–1987 average of 428. The Hurricane Hunters did not fly into any of the storms in 1987.〔 This was also the first year where tropical storm watches and warnings were issued instead of gale watches and warnings for tropical cyclones. 1987 was the last season that the Eastern Pacific Hurricane Center in Redwood City was responsible for forecasting in this basin, a task it had performed since circa 1972. The EPHC was folded into the National Hurricane Center, which took responsibility for the basin starting in the spring of 1988.〔(【引用サイトリンク】url=http://rda.ucar.edu/datasets/ds824.1/docs/format_ascii.html )〕 Only one tropical storm developed in June. In July, six named storms formed. Out of these storms, Hilary was the only storm to reach major hurricane status. The month of August had a total of five named storms, four of which became hurricanes. However, August did not feature any major hurricanes, though Hurricane Jova came close, peaking as a moderate Category 2. The month of September held the same number of named storms as August, with five named storms. The month also was the carrier of the strongest hurricane on record at that time (that had its intensity estimated from satellite imagery), Hurricane Max, a strong Category 4 hurricane. Hurricane Norma was a Category 1 hurricane on the Saffir-Simpson hurricane scale, which dissipated to the south of the Baja California Peninsula. The month of October featured only two tropical cyclones. The first system, Ramon, was a Category 4 hurricane. Very few cyclones this season impacted land. The only landfalling hurricane of the year, Hurricane Eugene was responsible for significantly damaging about 15 sq. mi of fruit crop, where damage estimated were at $2.6 million (1987 USD) In all, damage totaled to about $142 million. Tropical Storm Irwin, paralleled the coast of Mexico, causing flooding near Acapulco. Damage was totaled at $2.1 million (1987 USD). The remnants of Norma and Pilar produced rain over Baja California Sur. The remnants of Ramon brought extremely heavy rains to the Western United States.〔 A moderate El Niño was present throughout the season, with water temperatures across the equatorial Central Pacific was above normal.〔(【引用サイトリンク】title=Historical El Niño/La Niña episodes (1950–present) )〕 The Pacific Decadal Oscillation (PDO) was in a warm phase during this time period;. modern estimates place the PDO for 1987 at above normal. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「1987 Pacific hurricane season」の詳細全文を読む スポンサード リンク
